Abstract

A magnetic liquid grinder for polishing the surface of metallic or non-metal work-piece features that when there is no action of magnetic, its magnetic liquid can flow freely and when a magnetic field is applied to it, it can become a visco-plastic substance with a certain rigidity to form a flexible grinding layer on the surface of work-piece. The surface of work-piece can be polished by the relative movement between work-piece and said flexible grinding layer.

Description
